 In breweries, CO 2 is recovered as a by-product of fermentation. It can then be purified, compressed and liquefied for further use in packaging, tank counter-pressure, carbonation, or the preparation of dry ice block or pellets. Its many uses include:  The carbonation of beer, wine, soft drinks and mineral water;  The bottling beverages for preservation during transportation and shelf storage;  Tank pressurization

CO 2 Purification Carbon dioxide gas is passed through a CO 2 water wash scrubber to remove water soluble fermentation impurities. The gas then passes through an activated carbon bed to remove non- water soluble fermentation impurities - aldehydes, hydrogen sulfide, ketones, mercaptans, etc. After purification, the carbon dioxide is then compressed and dried to remove the water vapor. In the liquefying condenser, the CO 2 gas is liquefied to remove any remaining non-condensables (O 2, N 2 ). Courtesy of The Wittemann Company, Inc.
